So I own a 1989 brougham with the stock exhaust. I would like to put on some loud aftermarket exhaust pipes, but the flowmaster website has been very unhelpful. Does anyone know of a company that would carry loud aftermarket exhaust for my car, and if so, what specifically do I need?

 

You can design your own system with a little research and a local shop that will bend the pipes and install it all for you. Turbo Corvair mufflers from the mid sixies have long been the hot rod standard and most aftermarket mfg. make a design like this. You might also find something OEM that will work. I use two87 Bonneville mufflers on my 1973 LeMans GT and my son's friends say it sounds like a boat at idle so you get the idea, it barks! I think they still sell Cherry Bomb mufflers if you really want loud, Thrush, are they still sold, they were loud and were actually factory installed on the Rambler SC 390 back in 67.
